Hello all,
I'm planning a CNC lathe build. I've previously converted a 7x16 mini lathe (from Titan machinery) but found it lacklustre and largely unusable due to significant quality issues. Rather than spend more good time and money on my existing machine I'm going to build a new one.
I've acquired a piece of RHS 200x200x9 to form the bed.
Linear motion is in the form of profile linear bearings (beautiful things really) and ballscrews.
I'm looking for a spindle.
1. The option I'd like in an ideal world is a cartridge spindle such as http://ift.tt/1uVfiGA
This would be ideal because I can make a headstock, and just need to machine a mounting face and a bore for the cartridge.
There are a few issues with this:
a) Cost - looking at >$1000 plus shipping. I'll spend this if I need to, but it buys a lot of other stuff / tooling.
b) Shipping
- by air ~$400-500 and not available for all spindle sellers.
- by sea I've been quoted $100, but then I think I'll be faced with port fees, custom fees etc etc etc etc etc
c) Cost also puts it in to paying tax and duty territory.
d) They all use A2-4 spindles noses or similar. Not hard to make a collet chuck for, but I can't find 150-200mm chucks in Australia to suit, which adds another heavy import item. 'A' mount chucks seem much less common than D1-4 also.
2. Get a manual lathe spindle (new)
Pros:
Cheaper
More likely to get one than chucks are easier to match
Cons:
Machining more difficult
May be problematic to get
- I contacted Hafco - they don't keep any in stock and quote a lead time of 16 weeks. They didn't want to even mention a price.
3. Spindle +/- headstock secondhand
Could be good, could be a crap shoot.
Anyone got any suggestions?
Any particular preferences for spindle noses? I think I'd much prefer a D1-4 or A2-4 - quick and easy to change.
I'll likely be using a 4 Jaw and a collet chuck mostly.
